Where are you in TX? Mustang dyno I see? What kind of fuel was used? Do you plan to take it down the 1/4?

We have made 670rwhp through a stick with the 63lb SD injectors without breaking a sweat and no where near 100% DC.

We have seen higher gains than than with our street port and SICK gains with our race port and 102mm TB. Results coming in GM High Tech shortly

So many upgrade packages from different performance shops. Totally awesome. Again, the consumer wins. How deep are your pockets folks?

I agree about the 65lb injectors. Wasn't sure how this motor was going to respond in power. 80lb injectors are going in now.
I'm in Austin, TX at my profile says. No, it's not a Mustand dyno, it's a dynopak. 93 octane fuel was used and yes, I'll be taking down the quarter as soon as the car is done.


All dynos read differently, that's why I included the delta. So, what really matters is that we made 228 extra rwhp from stock.

Correct, the delta is important, but it is being inflated by the same percentage.
As fas as fuel systems and whp capacity, they only "see" uncorrected numbers when it comes to dynos. For that debate, I prefer to look at airflow in gm/sec or lb/min, but that stems from my turbo import days...

Met AUTOSOURCE TODAY(Looks like the owners of this car).

They told no less than 10 people that this car was 900 hp.

Challanged them to a race against ourI WHITE CTSV WAGON but they declined......I hate people that do this.

BTW-Our Little CTSV wagon ran 7.0 with just 630rwhp


Aspire might want to set the record straight,Dynapak dynos have very little loss)(they bolt to the hubs meaning the advertised numbers are pretty correct)

this is a great read.. i love when the shops come in and talk about results..

I see some crazy stuff going on with those dyno numbers.. 512 is higher than most stick cars iv seen.. and about 30-40 higher than the standered auto.
cant wait to see the MPH.. that car should run bottom bottom tens at 135 even with limited traction...

what kind of "crazy gains" have you see with this 102 mm tb upgrade (mine is done, sitting in the garage waiting to be tuned on wed.) just wondering..

It should be faster than that. If it indeed makes that much power.

These guy seem to have a high reading dyno, every auto trans I have seen stock, dyoned around 470rwhp, but every auto ZL1 I have seen on there dyno is around 510rwhp to 512rwhp. But regardless you gained around +225rwhp which is a great gain.

Still waitin on them vids!!

If the dyno is high for the base, then it may be high for the end result as well. This would put the auto car around 685 hp if adjusted down by the same percentage, which would be within range of what other mods by other vendors have achieved. It would be nice to see a dyno run of this car on another dyno.
